First, let me say I cannot (will not) live without our litter-robot. Sadly, however, after 2 years of trouble free use our LR is dead (and out of warrenty).
Recently we ran into two problems that did our LR in. The first problem was not fatal. A small rip in the rubber lining was allowing clean litter to be wasted. I had plans to patch this with a peace of rubber, but then a second fatal problem developed, leading to the untimely passing of our beloved LR. This problem occured suddently when the electronics totally freaked out. The LR no longer knows where to start and end it's cycle. At the end of the cycle the globe goes too far and dumps clean litter into the bottom before locking up and failing to return back to center. For now I'm manually running the LR by unplugging it until a new one arrives.
Since I have problems with both the globe and the base, and we need a working LR ASAP, I decided to go ahead and order a brand new unit. Even though the unit is dead after only 2 years, I still feel it was well worth the cost.
While we willing purchased a new unit, it's certainly not ideal. In the future it would be nice to see a more advanced version of the LR that could easily be serviced at home and cleanned more easily. Each of the major components should be snap-in modules that can be quickly overnighted and then snapped in placed by the customer. While I'm wishing for a better unit, the globe and base should easily open up (without tools) and come apart to allow easy access for both cleaning and service.
A snap-together design might also help the LR to get distributed on a retail basis with a lower cost. If all the parts of the unit were based on snap-together design then the unit could be packaged into a smaller box for easy retail distribution. Not having to rivet the thing together would also cut the cost of production, since the end user would snap-together all the peaces. In reality the LR is made of of very simple components, so a modular design shouldn't be all that hard to come up with.
